Proposal for official Holey Bytes C ABI.

Eg. What registers are reserved for what, what is saved by caller, what is saved by callee, integer sizes, etc etc...

Currently we have reserved:

  • r0 is a zero register, by spec unwritable, hard-wired zero
  • r1 as a return address, saved by caller
  • r2 as a stack pointer, saved by callee
  • r3 as a thread-local data base pointer
